Potential Applications:
1, It is a kind of silane coupling agent with multiple functional groups successfully used in rubber industry to improve modulus and tensile strength of rubber, to reduce the compound viscosity and save process
energy consumption.
2, It`s especially applicable for polymers with double bond or rubber formulation with hydroxyl fillers. The
suitable fillers include silica, silicate, clay, etc. The suitable rubber include natural rubber (NR), Butadiene
styrene rubber (SBR), Isoprene rubber (IR), Butadiene rubber (BR), Acrylonitrile butadiene rubber (NBR),
Ethylene propylene diene rubber (EPDM), etc.
3, Comparing with Silane ELT-S69, the low-active disulfane group in ELT-S75 guarantee its move reliable scorching safety.
Packing & storage:
1, painted Iron drum or plastic drum , net weight 200Kg each, 1000kg per IBC
2, Sealed well, store in a cool, dry place. Avoid light.
